Fixes#5593
Part of #5665
BREAKING CHANGE:
Number and content of UMD bundles have changed:
- we only publish one bundle that contains: core, common, platform/browser, http, router, instrumentation and upgrade
- exported names have changed and now:
- core is exported as `ng.core`
- common is exported as `ng.common`
- platform/browser is exported as `ng.platform.browser`
- http is exported as `ng.http`
- router is exported as `ng.router`
- instrumentation is exported as `ng.instrumentation`
- upgrade is exported as `ng.upgrade`
Closes#5697
